Revive Your BMW i3: OEM-Compatible Battery Replacement at 50%+ Savings
Is Your BMW i3 Losing Range at an Alarming Rate?
Imagine driving your BMW i3, only to find yourself stranded with only 150 kilometers of range instead of the promised 250+ kilometers. You’ve been through this before – the battery that once took you 200 miles on a single charge now barely makes it to work. You check the dashboard, and the battery health indicator is dropping faster than your morning coffee. What’s the real cost of replacing it? And is there a way to get genuine performance without paying dealer prices?
Why BMW i3 Owners Are Choosing CNS BATTERY for Replacement
The truth is, BMW’s original battery replacements cost over $12,000 for a 45kWh pack. But what if you could get a battery with identical performance using brand-new CATL cells at half the price? That’s exactly what CNS BATTERY delivers for BMW i3 owners worldwide.
Our OEM-compatible BMW i3 battery packs are engineered to match the factory specifications while providing superior value. We don’t use refurbished or recycled battery cells – we use brand-new CATL ternary lithium cells, the same quality used by leading automotive manufacturers.
The CNS BATTERY Advantage: Quality That Outperforms
✅ 50%+ Cost Savings Without Compromising Quality
- OEM battery: $12,000+ for a 45kWh pack
- CNS BATTERY: $6,000+ for the same capacity (savings of 50%+)
- Same CATL battery cells, same performance, same compatibility
✅ 2-Year/80,000km Warranty – Longer Than Most
Unlike other aftermarket brands with 1-year warranties, CNS offers a comprehensive 2-year or 80,000km warranty (whichever comes first). This means peace of mind for your investment.
✅ Perfect Compatibility Across All BMW i3 Models
Whether you drive a 2014 BMW i3 with 64Ah battery or the latest 2023 model, our battery packs are designed to fit seamlessly. We’ve verified compatibility for:
- BMW i3 2014-2023 (45kWh, 50kWh, 62kWh)
- BMW i3 REx (Range Extender) models
- BMW i3 2014-2023 with 64Ah battery
Real BMW i3 Owners, Real Results
“After the original battery degraded, the 4S dealership quoted €12,000 for a replacement. CNS provided a brand-new CATL battery at half the price. The range increased from 180km to 290km, and the 2-year warranty is a game-changer.” – Lisa K., Berlin, Germany
“I installed the 45kWh battery myself following the detailed video tutorial. The wiring was straightforward (6 power lines and 1 signal line), and the remote video guidance from CNS engineers was invaluable when I had a question. Now I only need to charge once a week for daily commuting.” – David L., London, UK
